Protesters, including Amnesty International, Greenpeace, some British politicians and the government of India are demanding that Dow, headquartered in Midland, Mich., pay $1.7 billion to victims of the release of chemicals at Union Carbide's Bhopal facility, the Detroit News reported Thursday.

The incident remained a part of history until Dow and the Olympics signed a 10-year sponsorship agreement in 2010, and what promised to be a fulfilling relationship for both parties is becoming a public relations nightmare for Dow, the newspaper said.

Although Dow has called the Bhopal disaster "a terrible tragedy" and says it "understands the lingering concern," it points out it had nothing to do with the disaster, that all liabilities have been settled and that any remaining issues should be directed to the Indian government, which took over responsibility for the site in 1998.

Still, "It would seem unwise for Dow not to acknowledge the anger and the viewpoint in London by these protesters," Rajeev Batra, University of Michigan marketing professor, said.

Roger Calantone, of Michigan State University's marketing department, pointed out that the longer the controversy drags on, the more difficulty Dow will have with negative publicity, the newspaper said.

Terrell Suggs tears Achilles tendon

BALTIMORE, May 3 (UPI) -- Baltimore Ravens linebacker Terrell Suggs told ESPN Thursday he tore his Achilles tendon during an offseason practice in Arizona and will have surgery.

Suggs said he was at his old high school in Chandler, Ariz., last week practicing the conditioning test required by the Ravens when he felt something turn and called for a doctor's exam, the sports broadcaster reported.

He said he expects to recover in four to six months, but the average return time to play in an NFL game is 11 months after Achilles tendon surgery, a study published by the American Academy Orthopedic Surgeons indicates.

"That's just going to make it so much sweeter when I run out of that tunnel and prove everyone wrong," Suggs told ESPN about reports he could miss the entire 2012 season.

"I've never had a real bad injury before -- sometimes you have to go through something like this to make you better."

"We are in contact with Terrell. He will see a specialist early next week and we'll know more at that time," the Ravens said in a statement.

More players sue NFL over concussions

ATLANTA, May 3 (UPI) -- A lawsuit against the National Football League filed Thursday in Atlanta by more than 100 former players alleges the league hid the dangers of concussions.

Jamal Anderson, Chris Doleman and O.J. Santiago are among the litigants. More than 1,500 former players are currently involved in suing the NFL over health issues, particularly head injuries, sustained during their playing days, CNN reported Thursday.

The latest lawsuit, filed by attorney Mike McGlamry in Atlanta's U.S. District Court, states the NFL "repeatedly refuted the connection between concussions and brain injury" and "downplayed and misrepresented the issues, and misled the players concerning the risks associated with concussions."

Similar suits against the NFL have been consolidated for a trial in Philadelphia, but no trial date has been set, the news service said.

The filing in Atlanta cites scientific evidence connecting concussions and Chronic Traumatic Encephalopathy, a neurodegenerative disease that results in memory loss, mood swings and symptoms similar to Alzheimer's disease. It points out CTE can only be diagnosed after a patient's death, and 12 cases of CTE have been detected in deceased former players.

Sandusky attorney seeks more information

BELLEFONTE, Pa., May 3 (UPI) -- The attorney for former Penn State coach Jerry Sandusky filed another motion Thursday asking the judge to compel prosecutors to turn over requested information.

Joe Amendola, defense attorney for Sandusky, who has been charged with sexually abusing 10 boys over 15 years, filed the motion in Centre County, Pa., Court for the second time, seeking documents and other information on the alleged victims in the case, which he says he has not received, the (State College) Centre Daily Times reported Thursday.

The motion reads in part, "The commonwealth has failed to provide the defendant with certain other discovery materials."

Amendola, accused by prosecutors of violating Judge John Cleland's order to keep the names of Sandusky's eight known accusers confidential, also filed court papers Thursday claiming he has "taken every reasonable step possible to maintain the anonymity" of the alleged victims, the Harrisburg Patriot-News said Thursday.

Sandusky has maintained his innocence of the charges. He is scheduled to stand trial in June.
